(2) The southern pine forest formerly extended from the Potomac River in a belt from one to two hundred miles wide along the Atlantic coast, across the Florida peninsula, and along the gulf of Mexico, skipping the Mississippi River and reappearing in a great forest in Louisiana and Eastern Texas. It was composed of almost pure stands of pine, the long-leaf, Fig. 46, the short-leaf, and the loblolly, with cypress in the swamps and bottom lands. In southern Florida the forest is tropical, Fig. 47, like that of the West Indies, and in southern Texas it partakes of the character of the Mexican forest.
